' rod 24 is disengaged from thekey pin 21 in.

the vertical: pin 17 whichlis motor driven through the eccentric operationjconnections described and as the oscillator blade 29 is connected with the cylindrical block 22 and knob A a i 26, itmay be readilyremoved to permit the handling ofthe tub in any desired manner,

or to be out of the way when handling the clothes while otherwise-c i r The blade 29 is as easily replaced bysimply inserting the block 22 into the recess 2 20.,

passingthroughthe wringer or pressing it down and swinging it untilthe i a key 21 engages thenotch 23, then the knob is turned to lock it in position.

The rotation of the shaft 9 operates-the eccentric sheave and connecting rod to rock a the pin 17 in its vertical bearing. The blade 29 beingrigidly connected with the pin 17 swings with anhscillating motion within are pushed back andforth in such a'manner the tub and the clothes placed within the tub i that the washing water is forced throughthe 7 it fabrics, the waterflowing easily through the holes in the blade. 7 V V 7 It has been found in practice thata washingma'chine constructed asdescribed, op erates quite successfully in the cleansing of the clothes, is very easilyhandled, and (as all i the operating parts are external to the. tub

and have no mechanical "connection, therewith, many difiiculties foundin other machines, both as to cost of manufacture and operation are eliminated, and-a simple, cheap and efiicient washingmachine is produced. a

' WVhat I claim as my invention is: Q1. In a washing machine, the combination of atub, a standard rigidly mounted beside said tub having-a vertically disposed power i driven shaft therein, said standard being en larged at its upper end to form a casing, a pin verticallyj ournalled in said casing, means in said-casing operatively connecting said shaft and pin to oscillatethe latter, and a 7 blade arranged in said tub having an iipi wardly and outwardly extending arm portion extending out over the top edge of said tub an detachably connected with said pin to be I oscillatedthereby,said blade being oscillated i V transversely of the tub axis from side toside i of the" tub.
